It seems I must have been asleep when I typed in the shooting info....

Correct info is 7D with 100 f/2.8L macro, ISO 100, f/32, 1.3 sec. Can view all this in EXIF info embedded in file.

The main point I was trying to make here was my desire for max DOF (f/32) and good IQ (ISO 100), which required somewhat long shutter speed (1.3 sec). Fortunately, there was enough available light and no wind to do this.

More of test. In hindsight, additional shots at wider apertures would have been instructive for comparison purposes. Still, wider apertures would have lowered the DOF, which I wanted to maximize in this case. Lots of detail in this tulip that I found interesting. The DOF trade at some point becomes an artistic choice, even considering some optical distortion - and not an absolute necessity.
